Cycles mixed material
I do a lot of similar things (book mockups with different finishings for presentations etc.). The way to go is definitely a setup in the same material. The idea is for each material to have its own shader and mix them together with a mix-shader-node and a bw-image (the white parts of the image represent one material, the black parts the other material).
If the logo changes you can simply swap the image for the mix-nodes.

This is the image I used for the mix-node:



This is the general node setup:


the blue part defines which parts are gold and which are bricks
yellow and red are the different materials (you can add normal maps, bump-maps, albedo etc...)




and the final result:
(I just grabbed a brick-texture for demonstration-purposes)



A few tips: to add realism you can use the mix-node-image as a bump-map for your gold-ink-material and mix the normal maps of the different materials.
you are also not limited to 2 materials, just add another material and another mix-node with a mask... unlimited materials. yay
